technical field

The utility model relates to a multi-well synchronous injection device for water injection well changing injection agent flooding, which belongs to the technical field of petroleum exploitation.

Background technique

Changing injector flooding in water injection wells is the most promising EOR technology in oilfields, and it has entered the field test or industrialization stage in many oilfields. The currently used injection device is relatively simple, including a liquid distribution tank, an agitator, a plunger pump and connecting pipelines. The injection process is to dilute the injectant in the liquid distribution tank, and the plunger pump is pressurized and connected to the wellhead through the pipeline to realize the injection. At present, the injection pipeline has only one channel, which can only be connected to one water injection well, and multi-well synchronous injection cannot be realized. Therefore, the research on multi-well synchronous injection device for water injection well changing injector flooding is still blank.
